You must use a professional contractor and you must receive pre-approval from CFU for thermal envelope improvements. CFU will pay incentives on residential attic insulation provided that the existing insulation level is less than R-30. Homes with R-30 or higher insulation levels will see little return on the investment in additional attic insulation. Rebates applications may be submitted for projects that increase the attic insulation up to a maximum of R-49.

You can use any licensed contractor to qualify for CFU's air sealing and insulation incentives. This list of contractors have provided proof of insurance and certification to CFU.
